General :: Player HLS (HTTP Live Streaming) Code Modification

I have source code from an appli running on android 3.2 with a WAMP Server and WowZa Server on my desktop. I have to make it accept the HLS (Http Live Streaming). I saw on the web that the Vitamio Library can do that so i used it. I know that natively, android 3.0+ do it well but i do not succeeded make it work successfully.

The player is successfully displayed but no video starts..After a reboot of my router (because my server didn't answer), the player crash each time.

Somestimes yes, sometimes no, i have some logs, they are as attachment.I think a buffer problem...

I think I have to implement this method (at the end of my code) but i know what type in it.public void onBufferingUpdate(MediaPlayer mPlayer, int percent)

IT WORKS VERY WELL WITH .MP4

Here's my code from the Player Activity :

Code:
package fr.niji.broadpeak.activity;
import java.io.File;
import java.io.UnsupportedEncodingException;
import java.util.ArrayList;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
/*import android.media.AudioManager;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnBufferingUpdateListener;

[code]....

Commented lines are the lines when i had still not used Vitamio.
